Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
convergent boundaries
True. Island arcs are formed due to the subduction of one tectonic plate beneath another, creating a line of volcanic islands. The volcanic activity in these regions is a result of magma rising to the surface from the subducted plate, leading to the formation of numerous volcanoes.
